Environment

  • Tableau Server 2020.2
  • TIBCO Data Virtualization
  • Windows Server 2019

Resolution

1. Uninstall TIBCO driver TDV 8.2
2. Remove driver entries in registry and system
HKEY_LOCAL_MACHINE\SOFTWARE\ODBC\ODBCINST.INI\ODBC Drivers  > TDV driver entries
HKEY_LOCAL_MACHINE\SOFTWARE\ODBC\ODBCINST.INI  > TDV driver folder
Windows\System32 > TDV driver dll file
Windows\System32 > TDV driver txt file
3. Install Composite 7.0

Using an extract can also be a workaround, if it can be switched from Live connection.

Cause

Newer version of driver called as TDV 8.2 causes the issue.
The issue does not happen with older version of driver (Composite)
 

Additional Information

  • The issue does not happen in Tableau Desktop (installed In Tableau Server machine)
  • The issue does not happen when extract is used
  • Increasing vizqlserver.session.expiry.timeout or proxy time out does not change the behavior
